Is dumbbell bench better in regards to safety, even muscle development, shoulder injury? I barbell bench'd 295 back in the day but it always seemed to hurt my left shoulder. So I just did dumbbell bench all the time, last rep at 120lbs on each side. Now I can barely do 45 lbs on the dumbbell bench cuz my left shoulder is hurts. It doesn't effect my tennis at all though. My chiropractor said to get mri, but I don't got $400 to burn and don't know if there's some other cheaper route I can go. Is there?
